Strange patch where filter doesn't work?

All my other patches, the filter operator (Z) works as it should. However I have this one patch where it simply does not do anything. I've tried changing every single setting I can find and even recreated the patch step by step as a new patch, duplicating every setting I could see from the old patch. In the new patch, the filter works just fine. All operators, effects, everything is (as far as I can tell) identical in both patches, except one the filter does NOTHING and in one it works fine. Anyone else experienced anything this bizarre? Is this an actual bug or is there something I could be missing? It's REALLY frustrating, as the original patch sounds every so slightly better (inexplicably) and not only that, but I created several patches based on that (the filter doesn't work in those either) that I would rather not attempt to recreate again, if I can get the filter to work in them.

 

Take a look at the FM-Matrix, if the Z within the Z-Operator icon is dark grey instead of white, you probably turned off the operator, right click on that icon toggles the status.

 

Nope, the operator is on and is the only thing that has the rest of the operators routed through it (i.e. there is no "dry" signal going to the mains). But the sound does play out, i.e. the operator is clearly passing sound as it should, but no filtering is taking place. None of the filter settings change the sound.

If anyone wants, I can send you the patch and you can see for yourself and try to get it to work.

 

You can attach the sound to your posting using that little clip symbol, but you have to zip it first.

 

Things to consider:

- what's the filter-routing? Are you tweaking a filter knob that isn't (an audible) part of the filter routing?

- compare filter scaling, filter envelope depth, filter velocity, or perhaps a controller in the mod matrix that's connected to the filter. it could be that the filter works but that it doesn't filter because it's composite frequency is way too high

 

Here is the patch in question (attached to this post)

I have tried changing the envelope depth, filter scaling, velocity, etc. Nothing has an effect. The composite frequency should also be pretty juicy, so it should be obvious when I turn the cutoff knob with everything set up as it is.

Have a look at the patch and see what you think.

 

Weeeeeiiiiiiiiiiiiiiird. And I've seen weird with FM8! It appears to be truly buggy, whatever I tried. And when making a new sound from scratch right after toying with this one, the filter works again..

Well, send it over to NI, and pray they're actually doing something about it..

 

Looks like a corrupted or manipulated file, since even if you normalize timbres, morphing doesn't work properly.

 

OK good, so it's not just me! I consider myself fairly skilled with FM8 and it was just really bothering me that I couldn't figure out what was wrong. If it's a messed up patch, I can accept that (even though it's not great news). I duplicated just about every setting into another patch where the filter works, so it's not a big deal (although this one sounds inexplicably ever-so-slightly different, not sure why).

Thanks for checking it out guys!

 

Thanks for this thread. I have a sound that does excactly this, was driving me nuts

So only workaround is to manually copy every parameter into a fresh patch? Good that FM8 has so few of them :-/
